Back in 2011, actress Carrie Fisher publicly announced that she had lost 50 pounds after participating as a celebrity spokesperson in the Jenny Craig Weight Loss Program. Besides good health, Fisher joked at the time that her other motivation was to fit back into the iconic metal bikini she wore for 1983 film, "Return of the Jedi."

"I want to get into the metal bikini and just walk around the house like an idiot," she told Ann Curry. "Answer the doorbell: 'What is it? This old thing?' ... I'll come out with a line of metal bikinis for women over 40. If you want dignity, you wear metal bikinis over (age) 40."

Unfortunately for Fisher, off the program she quickly gained back most of the weight she had lost. That is until last year, when Disney and director JJ Abrams announced that the 57-year-old would be reprising her role as Princess Leia in the upcoming "Star Wars 7".

"I'm glad they are doing a new movie because they are sending a trainer to my house so I can get in really good shape," Fisher told the Calgary Herald. "I'm really eating a lot of sugar in advance, as you can see. By the time I really get down to it, I will have eaten everything."

In an interview with "Extra's" Mario Lopez, Fisher's mother, actress and singer Debbie Reynolds, said all of her daughter's hard work has paid off with a 40 pound weight loss.

"She’s very excited about it ... she’s been on a diet ever since, because you know they have to be up to par, so she looks terrific," Reynolds said. "She's very excited, as we all are, because we all love 'Star Wars.'"

Star Wars: Episode VII is set to hit theaters on December 18, 2015.
